Authorization and capture with multiple currencies

Abstract

Techniques are presented for authorization and capture with multiple funding sources and currencies. A transaction amount associated with a target currency is authorized from one or more funding sources, where at least one of the one or more funding sources includes funds associated with a different currency from the target currency. The funds from the different currency are calculated at authorization to cover the transaction amount and converted at settlement or capture to determine if the transaction amount is still covered at capture.

1 . An authorization and conversion system comprising:
 at least one processor;   a memory in communication with the at least one processor, storing instructions that when executed by the at least one processor cause the at least one processor to perform the operations of:   storing at least one settlement policy and at least one mutually agreed threshold for a currency conversion between a buyer and a merchant;   receiving a transaction from a second party computer, for an amount in a target currency;   determining that funds in an account of the buyer in a source currency are insufficient to cover the transaction amount in the target currency;   based on the settlement policy, acquiring a balance of funds from an account of the buyer in a backup currency, wherein the backup currency is different from the source and target currencies;   acquiring a currency conversion rate for conversion between the source currency and the backup currency;   comparing a difference between the acquired currency conversion rate and an initial currency conversion rate with the mutually agreed threshold; and   authorizing the transaction based on the comparison.   
     
     
         2 . The system of  claim 1 , wherein the account of the buyer in the backup currency includes different available funds in the source currency or in the target currency. 
     
     
         3 . The system of  claim 2 , wherein the system includes a settlement and capture service to convert the funds in the account of the buyer in the source currency to the target currency when the transaction is consummated. 
     
     
         4 . The system of  claim 3 , wherein the settlement and capture service is to determine that the converted funds are deficient to cover the transaction amount in the target currency and acquire additional funds in the target currency from other funding sources when the transaction is consummated based on the determination. 
     
     
         5 . The system of  claim 3 , wherein the authorization and currency conversion system and/or the settlement and capture service assesses a fee to at least one of a buyer or a seller associated with the transaction for authorization and/or for settlement. 
     
     
         6 . The system of  claim 3 , wherein the settlement and capture service is to determine that a proposed conversion will produce a deficiency to cover the transaction amount in the target currency and, based on the determination, abort the transaction and release the transaction amount when the transaction is to be consummated. 
     
     
         7 . The system of  claim 1 , wherein the authorization and currency conversion system is to convert the funds in the account of the buyer in the source currency to the target currency using fixed currency rates available on a day that the authorization is processed. 
     
     
         8 . The system of  claim 1 , wherein the system includes a settlement and capture service to convert the funds in the account of the buyer in the source currency to the target currency using currency rates at a time of settlement or capture. 
     
     
         9 . The system of  claim 8 , wherein the settlement and capture service is to determine that the currency rates existing at the time of settlement or capture will produce a settlement amount that exceeds an authorized transaction amount to a certain or predefined percentage of authorization and, based on the determination, abort the transaction. 
     
     
         10 . The system of  claim 8 , wherein the settlement and capture service is to determine that the currency rates existing at the time of settlement will produce a settlement amount that is equal to or less than the authorized transaction amount and, based on the determination, consummate the transaction. 
     
     
         11 . The system of  claim 8 , wherein the settlement and capture service is to determine that the currency rates existing at the time of settlement will produce a settlement amount that exceeds the authorized transaction amount by a percentage of the authorized transaction amount and no additional funding is available to consummate the transaction and, based on the determination, abort the transaction. 
     
     
         12 . The system of  claim 8 , wherein the settlement and capture service is to determine that authorization is insufficient to cover the transaction amount at settlement or capture and the additional funds are converted when necessary to the target currency, and based on the determination, attempt to acquire additional funds from a backup funding source to consummate the transaction.

 converting the funds in the account of the buyer in the source currency to the target currency when the transaction is consummated.   
     
     
         15 . The method of  claim 13  further comprises:

         16 . The method of  claim 13  further comprises:

         17 . The method of  claim 13  further comprises:

         21 . The method of  claim 20 , further comprising at least one of:
 denying settlement when converting would produce a discrepancy;   using the account of the buyer in the backup currency to cover additional amounts when the transaction is more expensive in response to the conversion of the funds in the account of the buyer in the source currency; and   proceeding with the transaction at settlement when the conversion of the funds in the account of the buyer in the source currency are within a tolerance.   
     
     
         22 . The method of  claim 20 , further comprising:
